You're in a department store and you see a couple of attractive young women looking at a sweater．You listen to their conversation：

    “I can't believe it－Lorenzo Bertolla! They are almost impossible to find．Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome．”

    They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes．

    Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover marketing．Companies from Ford to Nike are starting to use it．

    Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation－consumers between the age of 18 and （3）It's a golden group．They have a lot of money to spend, but they don't trust ads．

    So advertising agencies hire young actors to “perform” in bars and other places where young adults go．Some people might call this practice misleading, but marketing executive Jonathan Ressler calls it creative．“Look at traditional advertising．Its effectiveness is decreasing．”It is true, because everyone knows an ad is trying to persuade you to buy something．However, you don't know when a conversation you overhear is just a performance．

    The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Interact or advice on staying healthy. We can even use it to learn a new language. We use the Internet to keep in contact with family and friends and stay in touch with issues we care about. The list goes on and on.

Well, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group—teenagers. So, try to be a responsible guardian for your children.

    The study results show that teens who spend at least 14 hours a week online are more likely to have high blood pressure. High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke. High blood pressure can also cause heart, kidney and brain diseases.

    The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred and thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first one to connect heavy web use with high blood pressure. Another research has connected that heavy Internet use with health problems including anxiety, depression and obesity.

    The lead researcher of the study is Andrea Cassidy-Bushrow. For the purpose of the study, she explains, teens considered heavy Internet users were online on average “25 hours a week”. In a statement she said, “Using the Internet is part of our daily but it shouldn't consume us.”

    Ms. Gassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smart phones and to do some kinds of physical activities. She also suggests that parents limit their children's use of the Internet to two hours a day, five days a week.

    In 1971 a young man who grew up very poor was traveling across the country, trying to make a new start for himself. Along the way he had completely run out of（用光了...） money and was forced to spend the night in his car. This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast.

    After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet. The waiter, who was also the owner, walked behind the chair where the young man had been sitting. He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,”the owner said. The young man couldn't believe his luck! He quickly paid for the breakfast, left a tip, bought gas with the change, and headed West.

    On the way out of town, he began to understand what the owner did. Maybe nobody dropped the money at all.“Maybe that fellow just knew I was in trouble and he helped me in a way that didn't embarrass(使尴尬)me. So I just made a promise to help other people if I can.”

    Later, he worked very hard and became a rich man. Now he lives near Kansas City. Each year he gives away thousands of dollars. He is known as the “Secret Santa” because at Christmas time each year, he personally hands money out to those on the street and at restaurants. Last year, he gave more than $50,000 away in Kansas City.

    In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn't much work there. Services such as hospital and transport are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.

    But in the big cities of Europe like London or Pads, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt of the city, and they are tired of the crowded streets, crowded trains and buses. They don't want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.

    So they move out of the cities. Some don't go very far, just a little way out of the city, to the towns near the cities, other people move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.

    Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don't make so much money and there isn't much work to do. People in the countryside are very different and aren't always very friendly.

    As a result, quite a lot of people who have moved to the countryside move back to the city. "

    It's wonderful to see crowds in the streets and cinema lights," they say.

The Museum of Science and Industry

    The Manchester Museum of Science and Industry will give us a more wonderful interpretation of the museum. The 2.8 hectare museum was rebuilt on the site of a huge Victorian warehouse and the world's oldest passenger train station. The number and type of collections are ranked first, and in the power exhibition hall, steam engines used during the Industrial Revolution can still be seen. The display of the railway here is rich and vivid in content. Understanding the history of the Industrial Revolution, the Manchester Museum of Science and Industry is a good choice.

    Power is the central theme of the museum, whether it is a bicycle or a steam engine, not to mention an old car. The history of mankind, as this museum shows, has been constantly running. All human inventions can't be separated from this idea. Life is also about exercise. All the exhibits in the museum are alive. The workers oil and wipe every day. Finally, steam is imported into the machinery to make them run as usual as they did a hundred years ago. Time is also reversed.

    In the power exhibition hall, the steam engine that had been used during the Industrial Revolution was still roaring, and the influence was not reduced. If you want to understand the Industrial Revolution and the role of Manchester in it, you must come and visit it, and you will find answers from the many wonderful exhibitions here.

    The Manchester Museum of Science and Industry completely reproduced the British Industrial Revolution, and ensured that the machines of its scientific and technological inventions operated daily, so that visitors and school children could experience the Industrial Revolution. Therefore, the museum has become an outstanding model for preserving industrial heritage.

    Manchester was known as Cotton Capital, Northern Capital, Second City, and Warehouse City for the Industrial Revolution. The Manchester Museum of Science and Industry is located in the center of Manchester City. It records the cradle (摇篮) of the Industrial Revolution with historical details. Manchester City's history, textiles, energy, communications, aviation, transportation and other industries have risen and fallen with the development of science and technology.
